Quilted Steel Pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of the Precision Steel Tube, no leakage under high pressure, high precision, high smoothness, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used for the production of pneumatic or hydraulic components, such as air cylinders or cylinders, Can be seamless tube. Our hot-selling products include Structural Steel Pipe, Fluid Steel Pipe, Boiler Steel Pipe, etc.
1. Description: Honed Tube is a kind of smooth bore Steel Tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder.
